It is true that the majority of Americans believe in god, but that doesn't mean the majority of educated thinkers do. In fact the majority of scientists do not believe in a supernatural god. Einstein himself did not believe in a supernatural god.
Also, I bet you didn't know that the founding fathers of America were in fact atheists. You claim my skeptism is "unhealthy", but I believe showing blind faith in something is alot unhealthier! Just look at the world around you, all the jihads going on in the name of religion, or blind faith. Now, you might claim that my blind faith in science is unjustified, however unlike other belief systems, science actually provides empirical evidence for its claims.
You also claim people have already undergone many of these tests. Then why have we not heard about the results? Surely an unbiased controlled experiment proving psychic phenomena (OBE's etc) to be real would have circulated in to the mainstream by now.
Stop bashing people who prefer to use their common sense instead of foolhardily accepting convictions without empirical evidence to back them up.
